Abstract

The invention discloses a powder charging and discharging device used for the charging and discharging during powder sterilization. The powder charging and discharging device comprises a charging hopper, a storage chamber, a Venturi tube and control valves, wherein the charging hopper is connected with the storage chamber through a control cavity and the storage chamber is connected with the Venturi tube through a control valve. The powder charging and discharging device has simple structure, lower cost and reliable performance, does not generate greater pressure fluctuation in the charging and discharging process and can be widely applied to the charging and discharging operation of powder.

Description

technical field [0001] The invention relates to a feeding and discharging device, in particular to a feeding and discharging device suitable for a powder sterilization chamber. Background technique [0002] When the powder sterilization room needs to enter and discharge materials, because there is a certain pressure in the sterilization chamber, a pressure separation mechanism must be used to realize the entry and exit of sterilized items. This separation mechanism is usually called the feeding and discharging device. There are many types of feeding and discharging devices in the prior art, however, the structures are generally complicated, expensive and poor in performance. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a powder feeding and discharging device. [0004] The purpose of the present invention will be achieved through the following technical solutions: [0005] A ...
